T 0 all whom it may concern:

Be it known that I, JOHN G. Boss, a citizen of the United States,residing at South Easton, in the county of Bristol and State ofMassachusetts, have invented certain new and useful Improvements inChanneling- Machines; and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

The present invention relates to improvements in channeling machines.

In the manufacture of welted boots and shoes the insole is usuallyprovided with a channel in its marginal portion and the edge of the soleis split to form a lip for the reception of stitches.

The present invention relates to improvements in machines for performingone or both of these operations upon a sole or an insole, and its objectis to simplify and improve the construction of such machines in therespects hereinafter pointed out.

Other objects of the invention will be noted in connection with thedescription of the illustrated embodiment thereof.

To the above ends the invention consists in the improved channelingmachine hereinafter described and defined in the claims.

In the drawings illustrating the preferred form of the invention Figure1 is a front elevation of the machine; Fig. 2 is a left hand sideelevation; Fig. 3 is a right hand side elevation; and Fig. 4 illustratesthe manner in which the knives operate upon the insole.

The illustrated embodiment of the machine comprises as its operatinginstrumentalities a channeling knife 1 and an edgeslitting knife 2,together with a work support 3 and suitable mechanism for actuatingthese parts to cause them to feed the work and cut the channel and theslit. The work support 3 is in the form of a truncated cone mounted on astem 4 journaled in a bracket 5 on the frame of the machine. The worksupport is mounted unyieldingly, the necessary adjustments for differentthicknesses of work being embodied in the parts by which the knives aresupported and actuated. The work support, therefore, forms a rigidsupport for the work and cannot yield to the thrust of the channelingknife. The work support performs the operation chine and connected withthe slide by a pinand-slot connection, as shown in Fig. 2. The lever 9carries at its upper end a cam roll engaging a cam 10 upon the shaft 11of the machine, and the cam roll is held against the cam 10 by a spring12 connected with the lever 9 and the frame of the machine. To preventretrograde movement of the work support a friction washer 13 is pressedagainst the stem 4 of the work support by a screw 14.

The channeling knife is arranged to vibrate transverse with respect tothe line of feed so as to cut the channel by a succession of choppingcuts which overlap to form a continuous channel. The knife is adjustablyfixed as shown in Fig. 3, by means of screws 15 engaging a horizontalslot in the knife, to a knife carrier 16 which is mounted on a lever 17by means of screws 18 engaging a slotin the knife carrier so as topermit vertical adjustment of the knife carrier. The lever 17 is pivotedat 19 upon a head 20 so as to have an oscillating movement, and the everthe thickness of the work may vary,

the head 20 is arranged to rise and fall, carrying the pivot 19 and, theparts mounted thereon with it, and such rising and falling movements arecontrolled by a presser .foot 26 fixed to the head 20 and bearing uponthe surface of the work. The head 20 is adjustably connected by ahorizontal shank 27 withan arm 28 pivoted at 29 on the frame of themachine and pressed downward so as to hold the presser foot inengagement with the work by a spring 30 connected with the frame of themachine by an adjusting screw 31. The shank 27 is slotted at 50 and abinding screw 51 passing through the slot fixes the shank in place. Bymeans of an adjusting screw 52 passing through the head 20 into the arm28 the head may be adjusted horizontally when the binding screw 51 isloosened, and in this way the position of the center of oscillation ofthe knife carrier may be adjusted horizontally so as to vary thedistance between the channel and the slit and determine the thickness ofthe between substance. The link 21 connecting the lever 17 and the slide23 permits rising and falling movements of the lever 17 and partscarried thereby without interference with the vibrating movementtransmitted to the channeling knife, and since the relation of thepresser foot 26 and the pivotal support 19 of the channeling knife isfixed the knife cuts always to the same depth below the presser foot,and thus its action is uniform whatever the thickness of the work. Thevertical adjustment of the knife carrier 16 on the lever 17 inconnection with the vertical adjustment of the presser foot permits thedistance between the channeling knife and the pivot 19 to be changed andin this way the center of oscillation of the knife carrier may beadjusted vertically and the radius of oscillation of the channelingknife may be varied to vary the form of the channel which is cut, andthe depth of the channel may be adjusted by moving the presser foot 26Vertically upon the head 20, the presser foot being for this purposeconnected adjustably to the head by screws 32 engaging slots in theshank of the presser foot, as shown in Fig. 3. It will be obvious thatthe form of the channel which is out can also be varied by thehorizontal adjustment of the head 20 and transverse adjustment of thechanneling knife 1 on the knife carrier 16. A horizontal adjustment ofthe head 20 followed by a transverse adjustment of the knife 1 changesthe angle of the cut with relation to the adjacent surface of the worksupport. In order to prevent accidental contact between the channelingknife and the work support when no work is in the machine a stop screw33 is arranged to limit the downward movement of the arm 28. Theedge-slitting knife 2 also operates by a succession of reciprocationstransverse to the line of feed so as to slit the soles by a series ofoverlapping cuts. The edge-slitting knife is mounted on a slide 34having bearings in a carrier 35 and it is actuated by a lever 36 pivotedon the frame of the machine and connected with the slide by apinand-slot connection. The upper end of the lever 36 carries a cam rollengaging a cam 37 on the shaft 11, and the cam roll is held against thecam by a spring 38 connected with the lever 36 and the frame of themachine.

In order that the position of the slit in the edge of the insole may bevaried, means are provided for adjusting the distance between theedge-slitting knife and the surface of the work support. The carrier 35is pivotally connected at 39 to the frame of the machine and its forwardend may be raised and lowered so as to change the path of movement ofthe edge-slitting knife. As it is usually desirable that the thicknessof the feather may be constant, an adjustable stop screw 4.8 isprovided, against which the carrier 35 may rest during the operation ofthe machine, being drawn downward by a springt connected with thecarrier by a screw 45, so that the distance between the edge-slittingknife and the work support remains constant as adjusted. If, however, itis desired to make the lip of the insole of constant thickness, it isnecessary to determine the position of the edge-slitting knife by theposition of the upper surface of the work, and in order that this may bedone when desirable a presser foot 10 is secured to the carrier by meansof adjusting screws 41 and 42 acting to draw the shank of the presserfoot against a pin 13 on the carrier 35. The presser foot is drawnagainst the surface of the insole by the spring 4 1 and maintains theedge-slitting knife at a constant distance from the surface since thecarrier 35 is free to rise and fall with the presser foot. l/Vhen themachine is operating in this manner the stop screw 48 is lowered so asnot to interfere with the movements of the carrier, but it may serve asa stop to prevent contact between the edge-slitting knife and the worksupport when there is no work in the machine.

An edge gage 46 for gaging the depth of the cut produced by theedge-slitting knife is adjustably mounted on the carrier 35 by means ofscrews 47 engaging slots in the shank of the edge gage.

In the operation of the machine the work is held by the operator uponthe inner surface of the work support, being pressed thereagainst bythepresser feet 26 and 40, and the rotation of the shaft 11 causes theknives to engage the work simultaneously and then to simultaneouslyretreat therefrom, and while the knives are out of operative engagementwith the work the work support is rotated through a small angle to feedthe work for the next out. As the thickness of the work varies thepresser feet cause the supporting and actuating mechanisms for theknives to rise and fall so that the paths of movement of the knives andthe cuts produced thereby have always the same position relative to theupper surface of the work.

A machine in which the channeling knife and the edge-slitting knifevibrate transversely to the line of feed has previously been proposed,and it is not intended to claim such a machine broadly, the presentinvention being directed to the improved means for feeding andsupporting the work and controlling the movements of the knives. Theseveral adjustments of the channeling knife and its actuating andsupporting mechanism permit the arrangement of the knife to cut achannel of any desired dept-h, form, and position. The use of a yieldingsupport for the channeling knife permits the use of an unyielding worksupport and edge-slitting knife carrier, where it is desired to make thefeather of constant thickness, whereby the construction of the machineis simplified, and it is new, so far as the applicant is aware, to mounta channeling knife vibrating transversely with respect to the line offeed upon a carrier arranged to yield in accordance with the thicknessof the work, whether in combination with a fixed or a yielding Worksupport.
